Magnetic domain structures of plastically deformed Ni/sub 3/Fe alloys

The magnetic domain structure of plastically deformed Ni/sub 3/Fe alloys has been observed in the ordered and disordered state. The magnetic properties of the plastically deformed Ni/sub 3/Fe alloys are influenced by two effects: the directional order in the antiphase boundary, and the strain field around dislocations. Domain patterns due to the directional order are observed in the fully ordered state, and those due to strain field in the disordered state.
